The main forms of Poker are Draw Poker and Stud Poker. In Draw Poker, all the cards are dealt face down to the players. In Stud Poker, some of the cards are dealt face up as the betting progresses, so that all of the other players get to see a part of each player's hands.
A phylogenetic tree or evolutionary tree is a branching diagram or  tree  showing the inferred evolutionary relationships among various biological species or other entitiesâtheir phylogeny âbased upon similarities and differences in their physical or genetic characteristics.
Molecular Phylogeny. Phylogenetics is the science of estimating and analyzing evolutionary relationships. Phylogenetic relationships among micro-organisms are especially difficult to discern. Molecular biology often helps in determining genetic relationships between different organisms.ne advantage of the molecular approach in determining phylogenetic relationships over the more classical approaches, such as those based on morphology or life cycle traits, is that the differences are readily quantifiable.
